1 INVENTOR i! JOSEPH E. CHAPL/MSR ATTORNEYS United States Patent 3,166,961 SHEET METAL ROOFING FASTENER BENBER Joseph Edward Chaplin, Sr., Lawton Ava, Savannah, Ga. Filed Sept. 13, 1963, Ser. No. 308,815 3 Claims. (CI. 81-15) This application is a continuation-in-part application of application Serial Number 227,603, filed October 1, 1962 and later abandoned.

This invention relates to improvements in sheet metal roofing installation apparatus and more particularly to a hand tool for bending an elongated fastener against a roof support member.

An object of the invention is to provide a device for bending an elongated fastener around a channel iron frame support member in a tight manner with little effort.

A further object of this invention is to provide a sheet metal fastener installation tool that will easily slide into and out from between the bottom engagement of the sheet metal roof with the support member and will bend the intermediate and lower portion of the elongated fastener about the support member.

A further object of the invention is to provide a hand tool of simple construction which is adjustable to accommodate various sizes of channel iron roof support members.

Still further objects and the entire scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that the detailed description and specific example is given by way of illustration only, and, while indicating a preferred embodiment of the invention, is not given by way of limitation, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

For a more complete understanding of the nature and scope of the invention reference may be had to the drawings, the specification and the claims.

In the drawings:

FIG. 1 is a perspective view on an enlarged scale showing the bending tool;

FIG. 2 is a modified exploded view of the tool with the bottom portion shown broken away and including intermediate extension members for one part;

FIG. 3 shows the tool bending an elongated fastener which extends through metal roofing supported on a channel member; and

FIG. 4 is a view similar to FIG. 3 with the bending tool in final bending position bending the lower end of the elongated fastener over the top portion "of the lower flange of the support member.

Throughout the description-like reference numbers refer to similar parts.

The bending tool is generally indicated at 10 and comprises a main body 11 having an inverted L-shaped member 12 with suitable spaced apertures 13 therein that are threaded to receive securing screws 14. The top 12a of the inverted L-shaped body member portion has attached thereto a handle 15 for hand grasping. Extending also from the main body member 11 and opposite to the handle 15 is a relatively thin tongue member 16 which is secured to the main body member by screws 17 which are fiat headed so as to make a smooth top surface. The screws also secure the handle 15 to the head 12a of the L-shaped body member 11. Also making up the body member 11 is an elongate back side member 18 having transverse aligning pins 18;:

therein in its lower portion for receipt in some of the dflhhfihl Patented Jan. 26, 1965 adjacent apertures 13 of member 12. Attached to the rear side of the back side, member 18 is a generally right angle fastener bender member 19 having a bent up hinged portion 1% which receives a second hinge portion 1% secured by screws 14, see FIG. 2, to member 18. The members 19a and 19b are secured by a hinge pin 19c. Attached to the lower end of the right angle fastener bender member 19 is a clamping lever member 20. This pivotal attachment is accomplished through a bent over hinge portion 19d at the lower end of member 19 which is slotted at 19a to receive an apertured intermediate portion 21M on the clamping lever member 20. A hinge pin 19 serves as a pivot for clamping lever member 20.

The clamping lever member 20 has a generally semi circular or G-shaped upper portion 20b which has a groove on its upper outer face 29c to fit against the adjacent lower end of the elongated fastener member such as 21 shown in FIGS. 3 and 4. The fastener member 21 is a special long nail-like member having a head 21a resting on top of the sheet metal roofing R through which the fastener extends downward-1y therethrough. The outer end of clamping lever member 20 serves as a hand grasp portion 29d.

Reference to FIG. 2 shows a more extensible body portion 11 for extending the effective length of the leg of the member 30, made up of a top inverted L-shaped member 30, intermediate extension inverted L-shaped members 31 and 32 and a back side member 18, the latter being the same as shown in FIG. 1. The members 30, 31 and 32 forming up the body member have suitable apertures in their main leg portion and in their transversely extending head portions such as at 3th: in member 31 for the head portion and 33b for the main leg portion. These apertures are threaded and receive the securing screws 14- as explained for the tool in FIG. 1. The tops of the inverted L-shaped members 31 and 32 are apertured so that these members when not in use may be stored along side member 36 with their top abutting along side the top of member 30.

The relatively thin tongue member 16 has a slotted aperture 16a extending in from the forward or leading edge 16b and this slideably receives the elongated sheet metal roofing fasteners 21.

Reference to FIG. 3 shows the use of this bending tool for installing the elongated fastener member 21 about a channel support member 33 having a top flange 33a, a bottom flange 33b and a web 33c. The sheet metal roofing piece indicated at R has the elongated fastener member 21 extending downwardly therethrough adjacent the support member 33 by abutting against its web portion 33c. The tool is installed by inserting tongue 16 between the roof R and the top side of flange 33a of the channel 33 with the slot 16a receiving the elongated fastener member 21. The generally right angle fastener bending member 19 is pushed by the operators hand against the elongated fastener 21 and bends the same about the channel member, 33 and the underside of the bottom flange 33b as shown inFIG. 3.

In FIG. 4 the clamping lever member 2t)- is further pivoted to bend the adjacent lower end 21a of the fastener member 21 about the top surface of the bottom flange 33b in a tight manner also pulling the fastener member 21 tightly against the Web 33c and the lower face of the bottom flange 33b.

intermediate members 31 and 32 as here shown, various sizes channel support members that may be accommodated about which the elongated fastener member 21 may be bent. There is illustrated, for example, in PEG. 2, accommodations for three inch, four inch, five inch Widths of channel members.

This tool is very efiicient in use, is easily handled in the hands of the operator and provides a tight and neat fastening of the fastener member about the support member yet permits easy removal of the tool as the relatively thin tongue member 16 is pulled out when the tool is drawn away from the work.
